Moving this from a downstream bug report:
https://gitlab.gnome.org/GNOME/evolution/-/issues/2525

When printing a page with system-set scaling other than 1.0 (I managed to reproduce at least under GNOME with gnome-tweaks->Fonts->Scaling factor set to 2.00, but I guess the screen scale for hiDPI might work similarly), then this scale factor should be ignored when sending the page to the printer, to save space and paper and toner and electricity.

This is with webkit2gtk4.1-2.42.0-1.fc38.x86_64

Steps:
a) verify the gnome-tweaks->Font->Scaling factor is 1.00
b) run from a terminal:
   /usr/libexec/webkit2gtk-4.1/MiniBrowser https://www.webkitgtk.org
c) once the page loads, use the menu button->Print
d) Choose "Print to File" and select the file, then confirm the print
e) quit the Minibrowser
f) set the gnome-tweaks->Font->Scaling factor to 2.00
g) repeat steps b), c), d), just save to a different file

I'd expect the files from d) and g) will be the same, but the g) file has larger font.
